Practice JLPTHow to tell them apart
ないで attaches to a verb and means doing something without doing the verb first, or softens a request not to do it (買わないでおきました, 帰らないで下さい). なくて is the て form of ない itself, so it links a negative state or action as a cause or reason for what follows (分からなくて困りました). Swapping them is wrong because ないで cannot express cause, and なくて cannot mean without doing.
- ないで Use ないで when you mean without doing an action or when asking someone not to do something.
- なくて Use なくて when the negative state or action is the cause or reason for what comes next.
